Rear 80/100-12 and Front 60/100-14 Tire and Inner Tube Set - Heavy

In this review the reviewer examines a two-tire kit intended for small pit and dirt bikes and explains who will benefit most from the set. The kit pairs a rear 80/100-12 3.00-12 and a front 60/100-14 2.50-14 tire with matching inner tubes and a TR4 straight valve stem, and its single biggest selling point is the complete, value-oriented package of tires, tubes and tools that fits a broad range of 70cc to 140cc machines. For riders who want a ready-to-fit replacement for common 12 in and 14 in rims, this kit is straightforward and economical.

Key Features

• Complete fitment: Includes both a rear 80/100-12 and a front 60/100-14 tire sized to fit 12 in and 14 in rims respectively, so buyers get matched replacements in one purchase.
• Included inner tubes: Each tire comes with an inner tube equipped with a TR4 straight valve stem, simplifying installation and reducing the need for extra parts.
• Tool kit and extras: The package includes a 4-way valve tool, spare valve cores and four valve caps, which helps with maintenance and small repairs trackside.
• Wide compatibility: The set lists fitment for many small-displacement models - from CRF70 and KLX110 to TTR90 and TaoTao DB14 - making it useful for owners of several common pit bikes.
• Durable material: Constructed from heavy rubber meant to be waterproof and wear-resistant, the tires aim to handle off-road conditions where traction and puncture resistance matter.

Who It's For

This kit is aimed at owners of small dirt and pit bikes with 12 in rear or 14 in front wheels who need a matched tire and tube replacement without hunting for separate components. It is a practical option for weekend riders, track-day participants, and fleet owners who value a low-cost, ready-to-fit solution that includes valve tools and spare cores.

Riders who demand premium longevity or race-level compounds should look elsewhere, because feedback indicates mixed durability and occasional inner tube issues; this set is best for casual off-road use, practice, or as an inexpensive spare set rather than long-term competition rubber.

Pros & Cons

Pros

Cons

• Not targeted at high-performance racing riders who need premium compounds and longer wear life.

Specifications

Our Verdict

The kit is a sensible, budget-oriented choice for casual riders and small-bike owners who need a matched front and rear replacement with tubes and tools included.
